Place it at the end of a sniper sequence, after Enemy Spotted sets up the target and the shot lands, then follow it with No God Please No for the victim's reaction and keep the focus on the kill.
About this sound
This is a short, roughly two-second voice line from the Sniper, delivered in a dry Australian drawl as a mocking thank-you to a target who stayed put. It feels smug, cheeky and a little cruel, the kind of line that lands after a clean hit. It comes from Team Fortress 2, where the Sniper says it after a kill.
